Perl SOAP::Lite call fails - perl

Question

I am trying to call a Soap Webservice.I have to pass the name of a Code table (for eg STATE_CODES) and it returns key value pair like NY - New york, DE-Delaware etc.
#!/usr/local/bin/perl
use strict;
use warnings;
use Data::Dumper qw<Dumper>;
#use SOAP::Lite trace=>'all';
use SOAP::Lite +trace =>'debug';
#use SOAP::Lite;
$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME}=0;
use Data::Dumper; $Data::Dumper::Terse = 1; $Data::Dumper::Indent = 1;
#my $wsdl = 'https://dev1:2001/ACTS?wsdl';
my $endpoint = 'https://qa1:2001/ACTS';
my $wsdl = 'HTTPS://QA1:2001/ACTS?wsdl';
my $method_name = 'impl:getCodes';
my $uri = 'http://impl.webservice.acts.ito.aoc.nj';
my $ns = 'http://impl.webservice.acts.ito.aoc.nj';
my $client = SOAP::Lite->new(
proxy=>$endpoint,
service=>$wsdl,
readable=>1
);
$client->outputxml(1);
$client->envprefix('soapenv');
$client->ns($uri,'impl');
$client->outputxml('true');
my #param;
push #param, SOAP::Data->name("codeTable"=>'STATE_CODES');
my $soapResp = $client->call($method_name,#param);
print $soapResp;
print "\n";
Output:

The soap request kind of looks good, but it gives error. I pasted the soap request into SOAPUI and it gave error. But as soon as i removed the line before the xml tag. in the soapAction, the request worked.
Why is my soap request resulting in failure. is it because of some certificate issue. i believe i have asked the code to skip certificate validation and Client-SSL-Warning: Peer certificate not verified in output above is just a warning and can be ignored.
